Injectivity surjectivity

WebbTesting surjectivity and injectivity. Since range ( T) is a subspace of W, one can test surjectivity by testing if the dimension of the range equals the dimension of W … WebbInjective is also called " One-to-One " Surjective means that every "B" has at least one matching "A" (maybe more than one). There won't be a "B" left out. Bijective means both Injective and Surjective together.

WebbWe are interested in its injectivity when k is a subfield of Q. For n = 0, this is conjectured by Bloch and Beilinson [2] (at least for cycles algebraically equivalent to zero), see also [20]. Note that the injectivity of (0.1) for smooth quasi-projective varieties would imply the injectivity of the refined cycle map in [32] (see also [1]).
